Latex Mold
Best casting medium for bas relief latex mold?
I carved a bas relif wall plaque (about dinner-plate size, perhaps 1/2 inch thick, with some fine and deep details) and made a fairly heavyweight latex-and-gauze mold of it. Now I'm trying to figure out what medium to use in casting the final product to be hung on a wall. I'm still not sure if I want a stonelike or antiqued silver finish, but first I need to cast it. Does anyone know what would be hard and durable at the dimensions mentioned, as well as relatively-lightweight enough to hang on a wall, with a surface that can be given a faux-material finish? And something that can be cast at home, without specialized furnaces or anything...
Plaster of Paris will work, yet it lacks durability. Hydro Stone is the greatest. I have used this to duplicate intricate antique picture frames with wonderful results. It will accept any kind of finish including faux finishes and accepts gold and silver leafing as well. It is also affordable and as easy to use as plaster of Paris. It is best mixed using one of thoses paint mixers that fit on a drill.
